Dusting Analysis
The maximum use concentration of 0.002% is a safety restriction imposed by the CIR Expert Panel due to potential 5-methoxypsoralen (5-MOP) content, not an indication of dusting for marketing purposes. This extremely low concentration may limit its functional impact for certain benefits, necessitating careful formulation to ensure efficacy within safety parameters.

- Ingredients that contribute to a finished product exceeding 0.0015% (15 ppm) of 5-methoxypsoralen (5-MOP).
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deems this extract safe for cosmetic use, provided finished leave-on products do not contain more than 0.0015% (15 ppm) of 5-methoxypsoralen (5-MOP) and are formulated to be non-sensitizing and non-irritating. Despite general safety, it carries a high concern for allergies and immunotoxicity according to EWG data, and can induce skin irritation or allergic reactions in sensitive individuals. Overuse may also heighten photosensitivity, thereby increasing sunburn risk.

Verdict
While offering antioxidant and astringent properties, its extremely low permissible concentration of 0.002% due to safety concerns regarding 5-MOP, coupled with potential for irritation and photosensitivity, makes its overall efficacy and suitability for precision formulations highly questionable.
